PATENT OFFICE.

FINE-FUEL-FEEDING APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 768,482, dated August23,1904.

Application filed January 6, 1904.

To all whom, it may concern:

Be itknown that I, MATIHS PRIGGA, residing at 33 Kurljandslaja, 15thQuartier, St. Petersburg, in the Empire of Russia, have invented new anduseful Improvements in Fine-Fuel- Feeding Apparatus,fof which thefollowing is a specification. y

My invention relates to a spray-producer which is chiefly designed forspraying massut to be burned in steam-generators and other apparatus.

In the accompanying drawings, wherein the4 invention is represented,Figure l is a vertical longitudinal section of a constructional form.Fig. 2 is a plan, and Fig. 3 is an end View, of the same. Fig. 4: is anend View of a modification. Fig. 5 is a vertical longitudinal section ofanother modification.

For the admission of the steamer a like medium required for the sprayingI provide a pipe rounded part to adapt the spray-producer for use inheating vertical steam-generators.

At the upper surface of the pipe a I provide a rim la, which leaves anopening toward the front-that is to say, above the slit d. rIhe rim /thas at its upper edge a flange to which the cap z' is secured. Anaperture j enables the pipe 0 to be inserted into the chamber formedbelow the cap vl. The massut-admission pipe o is beveled off at its endeX- tending below the cap and Hattened in front, where it is providedwith dents or teeth la, by which the massut issuing from the pipe c isdistributed over the surface By this spray-producer the massut may alsoIn the modification Serial No. 187,978. (No model.)

be sprayed with the aid of compressed air instead of steam. In Acase thedimensions are increased the compressed air may be employed for sprayingcoal-dust, sawdust,or the like, which is to be burned. 'Ihe coal-dust isfed to the apparatus under the action of gravity.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. A spray-producer for massut, coal-dust and the like, consisting of asteam-pipe having a flattened front part and terminating at the outeredge in a slit, a rim surrounding the upper surface of the said frontpart, a massutadmission pipe extending substantially at rightangles toand terminating above this su rface and having a dented edge bearingupon the same, substantially as herein set forth.

2. A spray-producer for massut, coal-dustand the like, consisting of asteam-pipe hav- Aing a flattened front part and terminating at the outeredgein a slit, a rim surrounding the upper surface of the said frontpart, a massutadmissionpipe terminating above this surface and having adented edge bearing upon the same, a cap provided above the Hattenedpart of the steam-pipe and secured to the said rim upon such flattenedpart, said massut-pipe eX- tending through the opening in the cap andtoward the said surface, substantially as herein set forth.

3. A spray-producer for massut, coal-dust and the like, consisting of asteam-pipe having a flattened front part and terminating at the outeredge Vin aslit, a tongue interrupting the said slit, a rim surroundingthe upper surface of the said front part, and a massut-admission pipeterminating above this surface and having a dented edge bearing upon thesame, substantially as herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

. MATIHS PRIGGA.
